PAPER-STOCK MACHINE.

Specification of Letters Patent.

I Patented Aug. t, 191% Application filed December 20, 1916. Serial No.138,080.

To all whom z'tmay concern:

Be it known that I, OTIS H. FoLsoM, a citizen of the United States,residing at Waterville, in the county of Kennebec and State of Maine,have invented new and useful Improvement in Paper-Stock Machines, ofwhich the following is a specification.

The invention relates to a paper stock machine.

The primary object of the invention is the provision of a machine ofthis character wherein the same is operated with minimum power and theparts are free from wear and the interior thereof is readily accessibleon the raising of the screen plate tank from the vat.

Another object of the invention is the provision of a machine of thischaracter wherein the screen will efiect a saving in the screening ofstock and the stroke of' the screen is readily adjustable to allowproper action for different grades of stock.

A further object of the invention is the provision of a machine of thischaracter wherein the paper stock will be acted upon through the mediumof a suction and compression effect through the action of rockingmechanism in a liquid sealed chamber so that the stock will bethoroughly screened prior to its discharge from the machine.

A still further object of the invention is the provision of a machine ofthis character which is simple in construction, thoroughly reliable andefficient in operation, strong, durable and inexpensive in manufacture.

Other objects will be in part obvious and in part hereinafter set forth.

The invention accordingly consists in the features of construction,combination of elements and arrangement of parts which will beexemplified in the construction hereinafter described, and the scope ofthe application of which will be indicated in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation of a machine constructed in accordance withthe invention;

Fig. 2 is an end elevation thereof;

Fig. 3 is a top plan view;

Fig. 4 is a vertical longitudinal sectional view through the machine;

Fig. 5 is a vertical transverse sectional view through the machine.

Similar reference characters indicate corresponding parts throughout theseveral views of the drawings.

Referring to the drawings in detail, A designates generally thesupporting frame which includes the spaced vertical uprights 10, upperand lower side beams lland 12 respectively, and a cross end piece 13,which latter is fixed to one pair of the uprights 10 at the upper endsthereof, the beams being secured to the uprights 10 in any suitablemanncr, and connected to the cross end piece 13 and the uprightssupporting the same are hinges 14 which swingingly support a screenframe 15 in which is arranged a reticulated plate 16 forming a screen,while fixed to the walls of the frame 15 below the screen 16 is a hangerframe 17 supporting which is fixed in a cross piece 20 in the hangerframe 17 the partition being designed to divide the shell 18 intochambers 21 which form compression and suction chambers for a purposepresently described.

Journaled centrally in the upper beams 11 is a rocking shaft 22supporting a rocking tank 23 providing a liquid vat into which dependsthe shell 18, and interiorly of this vat are fixed displacement boxes 24which work within the respective chambers 21 and serve to alternatelyefiect a suction and compression on the rocking of the vat in a mannerand for a purpose presently described.

Secured to the bottom of the tank constituting the vat 23 aresubstantially V- shaped hangers 25 constructed to receive the cross pins26 of an eccentric throw rod 27 "which 'is connected to an eccentric pin28 adjustably mounted in a wheel 29 journaled in a standard 30 supportedupon arest 31 therefor fixed to the lower beams 12 of the support. Alsomounted upon the lower beams 12 are rests 32 for a motor 33 preferablyof the electric type, which operates a drive belt 34 trained over thewheel 29 so that motion from the motor will be imparted to the saidwheel 29 and its motion will be converted from rotary into reciprocatorymovement by the eccentric rod 27 which rocks the tank 23 for a purposepresently described.

Fixed to the upper beams 11 near opposite ends thereof are platforms 35upon which are mounted expansion springs 36, the same vat 23apredetermined height to form a liquid seal between the shells 16 and thesaid vat and thereafter the paper stock is fed into the screen frame 15.When the motor 33 has been started the vat 23 is rocked on the shaft 22and by the rise and fall of the displacement boxes 24 an alternatesuction and compression will be effected in the chambers 21 in the shell18 therebydrawing the stock through the perforations in the screen plate16 into one'chamber 21 and forcing under pressure the stock within thevat 23 upwardly through the screen plate 16 through the other chamber21, and this operation is continuous, as will be apparent. It will beobvious that when the vat is in motion the stock is being drawn downthrough the screen at one end, while at the opposite end it is beingcleaned, and this allows a continuous stream of screenstock to flow outthrough the spout at the side of the machine. Fixed exteriorly aboutthe. shell 18 is a fender 38, the latter being stationarily mounted uponthe frame 17, while carried by said shell 18 and surrounding the same isa fender 39, which fenders cooperate With each other to prevent thesplashing of the stock from the vat during the operation of the machine.

From the foregoing description, taken in connection with theaccompanying draw ings, the construction and operation of the hereindescribed paper stock machine will be readily apparent and, therefore, amore extended explanation has been omitted.

Having thus described my invention, I claim:

1. A paper stock machine comprising a rocking vat, a screening frameabove said vat, a shell depending from the screening frame within thevat and forming compression and suction chambers, and means with in thevat and working within the chambers to effect alternate suction andcompression therein.

2. A paper stock machine comprising a rocking vat, a screening frameabove said vat, a shell depending from the screening frame within thevat and forming compression and suction chambers, means within the vatand working within the chambers to effect alternate suction andcompression therein, and means for rocking the vat.

3. A paper stock machine comprising a rocking vat, a screening frameabove said vat, a shell depending from the screening frame within thevat and forming compression and suction chambers, means within the vatand working within the chambers to effect alternate suction and.compression therein, means for rocking the vat, and shock absorbersacting upon the vat.

4. A paperstock. machine comprising a rocking vat, a screening frameabove said vat, a shell depending from the screening frame within thevat and forming compression and suction chambers, means within the vatand working within the chambers to effect alternate suction andcompression therein, means for rocking the vat, shock absorbers actingupon the vat, and fenders on the vat and shell to cooperate with eachother for preventing splashing of the contents of said vat.

' 5. A paper stock machine comprising a rocking vat, a screening frameabove said vat, a shell depending from the screening frame within thevat and forming compression and suction chambers, means within the vatand working within the chambers to effect alternate suction andcompression therein, means for rocking the vat, shock absorbers actingupon the vat, fenders on the vat and shell to cotiperate with each otherfor preventing splashing of the contents of said vat, and a deliveryspout leading from the vat.

In testimony whereof I aflix my signature. OTIS H. FOLSOM.
